Is It Safe To Spay a Pregnant Cat? 2023 Guide

is it safe to spay pregnant cat?

Spaying and neutering are common procedures for our beloved pets. They help curb certain behaviors driven by hormones and prevent unexpected litters of puppies or kittens. However, deciding to spay or neuter your pet is not always a straightforward choice.

For instance, if you have a female cat that hasn’t been spayed, she’ll typically experience her first heat between 4 and 6 months of age. This might not be a big concern if your cat stays indoors and you don’t have any intact male cats nearby.

But if she goes outside or there are intact male cats around, you could find yourself dealing with an unexpected pregnancy. Sadly, many kittens born from such surprise pregnancies end up as strays or in shelters, struggling to survive.

Now, there’s an ongoing debate about whether it’s a good idea to spay a pregnant cat. Technically, it can be done, but it involves aborting the unborn kittens. This guide of  Toronto North Animal Hospital will walk you through everything you should consider before making this decision for your cat.

Is it Possible to Spay a Pregnant Cat?

Spaying a pregnant cat follows a similar procedure to spaying non-pregnant cats, but there’s a crucial difference: it involves aborting the developing kittens. This aspect of abortion is a deeply contentious and divisive issue, which contributes to the uncertainty surrounding the practice of spaying pregnant cats. The debate revolves around two conflicting perspectives, making it a complex issue to navigate.

On one hand, proponents of spaying pregnant cats argue that aborting the pregnancy prevents more kittens from entering an already strained system of foster homes, shelters, and rescues. This, they contend, offers the cats already within the system a better chance of finding permanent homes rather than facing euthanasia.

Conversely, there are those who oppose taking any lives, even those of unborn kittens. They argue that it’s morally acceptable to allow the pregnancy to run its course and then spay the female cat after she has given birth.

Despite the arguments against spaying pregnant cats, it’s worth noting that the procedure is often performed successfully and is considered safe. The primary difference compared to standard spaying surgeries lies in the presence of fetal kittens.


Overpopulation Control: Rescuing and spaying a pregnant cat helps combat the issue of overpopulation in feline populations.

Health and Adoption Advantages: Spaying very young or elderly pregnant cats increases their chances of adoption and overall well-being while reducing the risk of orphaned kittens, who often struggle to survive and require extensive care.

Limited Homes for Homeless Cats: The sad truth is that there aren’t enough homes available for the vast number of homeless cats. Spaying a rescued pregnant cat reduces her shelter stay, making her available for adoption sooner.

Euthanasia Prevention: Shelters often face difficult decisions when space and resources become scarce. Spaying helps reduce the need for euthanasia.


Counterargument for Adoption: Some argue that kittens are highly adoptable and will always find homes.

Ethical Concerns: Animal rights activists contend that allowing a pregnant animal to give birth and caring for her young is more ethical as it aligns with their natural lifecycles.

Foster Networks: Many organizations have extensive foster networks in place, allowing them to place pregnant cats in temporary homes until their kittens are weaned. This approach prevents these cats from consuming valuable shelter space and resources.

How to Make the Right Decision Regarding Spaying Your Pregnant Cat

Determining whether to spay your pregnant cat requires careful consideration of several key factors:

Assess the Pregnancy Stage: Understanding the stage of your cat’s pregnancy is crucial. Early and mid-term spaying and abortion are common practices, but late-term abortion is generally avoided. If it’s your pet, you can estimate the stage by tracking her last estrus cycle (heat). Otherwise, consult a veterinarian for an accurate assessment.

Consider Age: The age of the cat matters. Very young cats (under one year) and older cats (eight years and older) are more prone to birthing complications, including deformed or stillborn kittens, or the mother cat’s health being at risk. A thorough evaluation by a vet can help determine the potential risks.

Evaluate General Health: The overall health of your cat is essential. In cases of good health and late-term pregnancy, you might decide to allow the pregnancy to proceed to birth, depending on other factors. However, if the cat’s health is compromised, pregnancy, childbirth, and nursing may pose significant risks. Consult your veterinarian to assess the cat’s health status before giving birth.

Assess Your Household: Preparing for newborn kittens is a substantial commitment. If you have a secure and quiet room where you can isolate the mother cat and kittens, shielding them from other pets, small children, or disturbances, it can be manageable. In the case of a stray, it’s often best to involve local rescue organizations with the necessary expertise.

Consider Placement: Evaluate your ability to find suitable homes for both the kittens and the mother cat. If you have the resources and space to accommodate more cats and are financially prepared to care  them after spaying, keeping them may be a realistic option. If your intention is to rehome the kittens, be diligent in your screening process to ensure their future well-being.

Prioritize Humane Treatment: In cases involving a pregnant feral or stray cat, determining the most humane course of action is vital. Consider whether it’s more humane to spay and release her back into her familiar environment or to embark on efforts to rehabilitate her for potential adoption, with or without her kittens.

When to Consider Spaying a Pregnant Cat

While it remains a topic of debate, there are compelling reasons why spaying a pregnant cat may become a necessary choice.

Addressing Overpopulation:

In many cases, animal shelters and rescue organizations opt to spay or neuter incoming cats, even if they are pregnant, to prevent future pregnancies. This decision stems from the reality that these facilities often operate at full capacity, and the arrival of a litter of kittens can strain already limited resources. This action is taken to ensure that older cats in need of homes also have a chance.

Moreover, intact cats can quickly become pregnant again, sometimes even while still nursing their current litter. With a gestation period as short as 63-65 days on average, they can potentially go through multiple pregnancies in a single year. This rapid reproduction contributes to the high numbers of cats in shelters or living on the streets.


Consideration of Age:

Pregnancy comes with various health risks, especially for young or elderly cats. These cats may not be sufficiently developed or may be too old to safely bear and raise kittens. This also applies to cats that are not in a healthy enough condition to carry a litter to full term. In such cases, opting for abortion and subsequent spaying is a safer choice. While it does involve terminating the fetal kittens, it ensures the well-being of the adult cat, sparing her from potential illness or mortality related to the pregnancy and birthing process.


Sum Up

Spaying a pregnant cat is a viable medical procedure and poses no greater risk than spaying a non-pregnant cat. However, the primary ethical concern revolves around the fate of the developing kittens. When you opt for spaying a pregnant cat, you’re essentially choosing to terminate the pregnancy, which is a deeply contentious issue for many individuals.
